Headers and dual exhaust along with an intake upgrade will increase the engine top end power a bit. A cam and high flow heads will increase it a lot.
The most notable performance would be to change to a stronger cam ( More Horsepower ) Cam & lifters , Timing chain set and new valve springs If you don't change the springs you are taking a chance that you are going to break an old spring because the new cam will probably have more lift than the old spring can handle I learned this lesson the hard way The valve hung open got smacked by the piston broke the skirt blew out a cylinder wall and bent the crank PS Have the cam degreed in
